So what you're saying is, I can measure any place on a floor, any where in the room, and it should be no more than 6' from a receptacle, OR, is it measured any where along the line at the bottom of the wall, even if you measure from one wall across a corner to another wall, should be no more than 6'?
Neither, if you meant "diagonal" when you said "across a corner". This is strictly along the wall/floor line, the perimeter of the room.
Any point along the wall must be within 6' of a receptacle. Going around inside or outside corners is okay, but not diagonally away from the wall.
I call it the "6-12-12-6" rule, and on kitchen counters, it's the "2-4-4-2" rule. The former applies to any wall space 2' or wider, and the latter to 1' or wider.
